ISO Shootout: Canon 5D Mark IV vs Canon 5DS R (Dolls)

See my Canon wish list and other wish lists at B&H Photo.

The about $3499 Canon 5D Mark IV is just out and this is my first formal look at it.

No doubt it will delight some shooters for its somewhat higher resolution over the Canon 5D Mark II and especially for its dual-pixel autofocus chops, but just how well does it do on noise compared to the Canon 5DS R?

Canon 5D Mark IV ISO Series from 100 to 25600 vs Canon 5DS R (Dolls)

Very large crops are shown from ISO 100 to ISO 12800 (and ISO 50 for the 5DSR and ISO 25600 for the 5DM4).

For comparison purposes, the Canon 5DS R is includes twice: dowsampled to 5D Mark IV resolution, and also at native resolution. This study is really useful I think, because of the relative comparison with the 5DS R.
